More and more voip providers are these days offering free trial credit or Free minutes to make voip calls. Today we discuss about another voip provider "Teletwits" which is offering free $2 credit to make free international calls.

Before we go into details about Telewits its feature and calling procedure, first a mention about Free calling minutes offered by them.

Telewits is offering free $2 credit to all new users, this credit is worth approx 50-60 minutes of free calls to India. In order to get this free credit by Telewits.

1. Sign up with Telewits.2. Confirm/validate your account.3. After your account is created, you will see $2 credit in your account.

Now Telewits promises excellent voice quality, however I have tested this service and the voice quality is not that great, though not bad either.

How to make calls using Telewits :1. Make calls using Local access number. This is very similar as making calls using your normal calling card.2. Make SIP Calls. Configure SIP on your mobile and start making SIP calls. Try with Fring or Nimbuzz.

You can make free mobile calls using your iPhone, Android device or iPod touch using SIP. It works great! Atleast try the Telewits free calling minutes and you may continue with it (by buying voip credit) if you like the service.
